Get a file without name in url

I would like to get the file from this url : https://donnees.roulez-eco.fr/opendata/instantane
As you can see there's no file name in the URL.
My problem is with this simple code :
var file = fs.createWriteStream('./myFile.zip')
http.get(url, function(response) {
response.pipe(file);
}
This code works well if you got an url like https://someurl.com/filename.zip.
The file is downloaded and can be use but this response.pipe(file) line throw me this error:
events.js:163
throw er; // Unhandled 'error' event
